This implements storing named captures on the regexp result object.
For instance, /(?<a>.)/u.exec("b") will return a result such that:
result.group.a // "b"
The spec proposal is not yet final, so this may still change in the future.

Create different json files for diffferent optimization attempts of the same function.
This allows to analyze the graphs of early optimization attempts that lead to deopts or to produce a proper json file in the case of a deopt loop.

In this particular case, we just did a (lhs)op(rhs), ignoring the case
that lhs and rhs might have different signedness.
This CL changes that to use the proper Cmp##op##Impl implementation,
which does two comparisions for signed-vs-unsigned checks, avoiding
compiler errors.

E.g., ast/ast.h uses Label but shouldn't need to include assembler.h for that. With
this change, we can hope for proper layering in the future (not quite there
yet).

Test that setting breakpoints works for wasm, and that they are hit
correctly.
This basically tests all the layers involved: Compiling and running
wasm interpreter entries, passing arguments to the interpreter, storing
break point infos in wasm objects, getting the right BreakLocation from
wasm frames, and getting stack information from interpreted frames.

The index input of load and store nodes has to be of type int32. However
it is still possible that this index input was lowered by the
Int64Lowering, for example if the index was a kTruncateInt64ToInt32
node. With this CL we check if there exists a replacement of the index
and if so, use the replacement instead of the original index as the
input for the lowered load and store nodes.

Frame inspection is currently limited to locations of execution.
Further details like local variables or stack content will follow later.
The FrameInspector now stores a pointer to the interpreted wasm frame,
and redirects certain requests there, just as for deoptimized frames.
Hitting breakpoints is now also supported for wasm frames.

This patch adds destructor to ValueSerializerTest test fixture class
which reset unhandled scheduled exceptions thrown from the current test.
In some cases unhandled scheduled exceptions from current test (eg.
from one test from ValueSerializerTestWithWasm test case) produce that
Context::New(isolate()) from next test's constructor returns NULL.
This error is easily reproduced when unittest file (compiled for ARM or
MIPS simulator) is directly executed (not by tools/run_tests.py script),
so all tests are executed together. When the script is used, each test
from ValueSerializerTestWithWasm test case is separately executed and
unhandled exception from one test doesn't efect to another test from
the same test case.

Rationale:
- To do scope analysis based on PreParser, and use the result again when parsing
later, PreParser and Parser need to produce the same Scopes and variable
declarations in them.
- This is not the case for non-simple parameters: Parser creates an additional
inner Scope where the declarations were, whereas PreParser does
DeclareVariableName directly in the function Scope.
- So this CL fixes that by moving the Scope creation for non-simple parameters
into ParserBase.
- As a side product (and a partial proof that this change makes sense),
PreParser::ParseEagerFunctionBody is now gone.

The %_ClassOf intrinsic roughly corresponds to the deprecated ES5
[[Class]] internal property, and should not be used anymore ideally.
However since we still have quite a couple of uses of this intrinsic
in the self hosted JavaScript builtins, we would tank some builtins
like Map, Set, WeakMap, WeakSet, etc. quite significantly unless we
also support this intrinsic until the builtins are all migrated to
C++/CSA builtins.
